Creating a dry erase marker experiment is a great way for kids to explore the properties of different brands of markers and have fun in the process! To get started, you will need a few markers of different colors and brands, some white poster board or paper, and a few other materials.
Start by laying a white poster board on a tabletop. Spread the markers out on the board and ask your kids to think of a hypothesis about which brands of markers they think will work better. Have them draw a design on the poster board with each of the markers; use one color for each.
Once they’ve finished the designs, help them understand that using a dry erase cloth or tissue is a great way to remove the marks without damaging the poster board and that it can be used over and over again.
Have each of the kids take turns wiping away the markings made by each of the markers. This will help them see how the different markers perform under the same conditions and which ones come off easier.
After they’ve tested out all of the markers, have them evaluate and come up with a conclusion about which brands worked best and why. It’s also a great chance to discuss the science behind the experiment, such as the dye and pigment used in the markers and why certain types of markers erase better than others.
Not only is this experiment fun, but it also provides great educational opportunities for your kids. They’ll be able to explore the purpose of different markers, test out different brands, and draw their own conclusions about which ones worked best.
How do you make Expo marker float on water?
Making an Expo marker float on water takes some simple materials and a bit of creativity. First, you’ll need an Expo marker and a clear plastic cup filled with water, as well as two plastic straws. Next, cut one of the straws roughly in half and tape the cut end of the straw onto the back of the Expo marker.
Now, insert the other straw through the middle of the taped straw so that it forms an “X” shape. This will be the base of the marker. Place one end of the marker onto the surface of the water and gently push the other end down into the cup.
The marker should now float on the surface of the water, supported by the two straws. It’s a bit of a trick, but with a little practice, you’ll master it in no time!.
How do you make a stickman move with water?
Making a stickman move with water is a fun and creative science experiment for kids of all ages. To do this, you will need a few simple materials including a glass jar, an illustration of a stickman, and some water.
Start by drawing a stickman on a piece of paper and cutting it out so that it’s the same size as the glass jar. Make sure to draw the limbs as thin and long as possible. Then, pour enough water into the glass jar so that when you add the stickman, it floats.
Use a very thin tube, such as a straw, to blow air into the jar and create an air bubble around the stickman. This air bubble should cause the stickman the move around the jar. To make the stickman move faster and more freely, add more water to the jar.
Have fun experimenting with the motion of the stickman!.
Why does dry erase ink float on water?
The reason dry erase ink will float on top of water is because it has lower density than the water. This means that the ink is less dense than the liquid, so it cannot sink and has to float. Dry erase ink is composed of solvents and pigments resulting in the ink having a much lighter density than that of the water it is sitting on.
The solvents are comprised of lighter dense material that helps create the buoyancy effect. The pigments usually contain heavier oils, but the solvents dominate the make-up of the ink resulting in the overall lighter density.
This means the dry erase ink has a much lesser gravity compared to the water and is less responsive to gravity’s pull. This is why the ink is able to stay afloat and cause the floating effect.
Does Sharpie make dry erase markers?
No, Sharpie does not make dry erase markers. Sharpie permanent markers are generally alcohol-based, which are designed to be permanent on most surfaces. Dry erase markers are typically water-soluble, so they can be easily erased from most non-porous surfaces like whiteboards and glass.
They usually contain a base of glycerol/glycol and a colorant such as a dye or pigment. Sharpie produces a range of non-permanent pens and markers, like their highlighters, pens and permanent markers, but they do not manufacture any dry erase markers or whiteboard markers.
How do you revive a dry whiteboard marker?
Reviving a dry whiteboard marker is a relatively simple job. First, attach the dry marker to a dry cloth or paper towel. Then, dip the tip of the marker in warm water for about 5 to 10 seconds. After, shake off the excess water and rub the tip of the marker over a paper towel or cloth.
Test the marker on a piece of paper or a test sheet to check the ink. If it is still dry, hold it down to the warm water again and try a few times. You can use a blow dryer after it is submerged in the warm water, just keep it at a minimal distance and time.
If the marker doesn’t work, it may be time to invest in a new one.
How do you rehydrate Expo markers?
If you have dry Expo markers and need to rehydrate them, there are a few simple steps you can take to bring them back to life. The first step is to determine if the ink is actually dry. Sometimes markers appear to be out of ink and simply need to be vigorously shaken in order to redistribute the ink.
If the marker does require rehydration, the most effective way is to soak them in warm water for at least 4 hours. After 4 hours, the markers should be taken out and the felt nib should be gently squeezed and wiped with a cloth.
This will help to remove any excess moisture. Once that is complete, you can replace the lid and the markers should be ready to use. Be sure to shake and test the markers before use to make sure the ink is flowing correctly.
What happens if you put a marker in water?
If you put a marker in water, it will eventually dissolve. Depending on the type of marker and the water, the marker may not dissolve immediately, but it will likely transfer some of the marker’s colour to the water.
Depending on the medium within the marker, it could also create an oily layer on the surface of the water. These transference and dissolution processes will depend not only on the type of marker, but also on the type of water, the temperature of the water, and the amount of time that the marker is submerged.
For example, if the marker has a higher oil content, it may take longer for it to dissolve. Likewise, hotter water can help accelerate these processes.
